Bumping Lake

Bumping Lake is located southeast of Chinook Pass off Hwy 410 in the Wenatchee National Forest at 3,426 feet elevation.

This Bumping River impoundment offers good fishing for 6- to 9-inch kokanee starting in mid-May.  Rainbow, cutthroat and eastern brook trout are also available in this fishery, some up to 16 inches.  The lake is periodically stocked with rainbow and cutthroat trout fry.

The reservoir is closed to fishing for bull trout.  Please carefully release any bull trout that are inadvertently hooked. 

There are excellent public camping facilities at the lake, plus a good boat ramp (managed by USFS), with a private resort (Bumping Lake Marina) that includes a fee-based launch on the northern side of the lake across the dam.  Lake water levels are lowered in the late summer- early fall for downstream irrigation needs and so boat access is reduced. Statewide minimum size / daily limit. Chumming permitted. Always check lake fishing regulations.

Two-pole fishing is allowed

Shoreline access: Good - Good shoreline access around the lake on U.S. Forest Service land.

Fishing prospects calendar

Rainbow trout

Fishing success for Rainbow Trout is generally best in the spring when thousands of fish are stocked statewide, but they can be caught year-round in most waters with a little patience and persistence. Success remains high into June and gradually declines as water temperatures increase and fish move offshore to stay cool. Fish that escaped the spring harvest return to the nearshore areas in the fall as waters cool off. Some waters may also be stocked again in the fall further boosting catch rates.

The Kokanee fishery typically lasts from April-October before the adults leave the lake to spawn in tributaries starting in late-October and early-November. Fishing is best in the spring before they move into deeper water to avoid warming water temperatures, but they can be targeted throughout the summer in deeper offshore areas near the thermocline. There may be a slight uptick in some waters in the fall as adults return to shallower water and move near shore towards spawning tributaries.
